Determines the cause of renal failure. Similar to the FENa, but can be used on patients on diuretics.
Fractional Excretion of Urea (FEUrea) = (SerumCr * UUrea ) / (SerumUrea x UCr) %
This test can provide similar information to the FENa equation, but can still be used in patients on diuretic therapy (diuretics alter the sodium concentration, making the FENa equation unusable).
